Windows Server SSD Optimisation
How to optimise Windows Server for SSD Drives and reduce the Write IO to increase the lifespan.

1) Enable TRIM
Run the command “fsutil.exe behavior query disabledeletenotify” to check the status.
Should show result of “DisableDeleteNotify = 0” (enabled)
Windows should automatically enable TRIM on your SSD Drive, if it does not then run the following command to enable it:
fsutil behavior set DisableDeleteNotify 0

2) Disable Prefetch
Open Regedit:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
EnablePrefetcher = 0

3) Disable Superfetcher
Stop and disable the Superfetch Service

4) Disable Indexing
Stop and disable the Windows Search Service (WSearch)

5) Disable Write Cache (not used by SSD Drives)
Under Computer Management, Device Manager, Drive Properties, Policies:
Disable (uncheck) Enable write caching on the device and which will also disable Turn off Windows write-cache buffer flushing on the device

6) Turn off System Restore for the OS Partition
Under Control Panel, System, Advanced system settings, System Protection tab:
Highlight the Partition and click on Configure and select Disable system protection

7) Turn off Hibernation (may be tuned off already if Hyper-V is installed)
Run the command “powercfg –h off

8) Set the Page File Initial Size and Maximum Size to the same Maximum figure.
IE: If you have 32GB RAM then the Initial and Maximum should be set to 49152 (1024 x 32 x1.5) (48GB).

9) Disable Defrag
Stop and disable the Disk Defragmenter Service.
